[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-9 A continuous shrimp shell grinding device comprises a base 1 and a grinding cylinder 2 fixedly mounted on the base 1, a collecting box 3 is slidably mounted on the bottom end of the grinding cylinder 2, a servo motor is fixedly mounted in the base 1, a central shaft 4 is fixedly mounted on the output end of the servo motor, the central shaft 4 is hollow, and a slider 62 is vertically slidably mounted inside the central shaft 4, a first fine wire 63 is fixedly mounted on the slider 62, and a second fine wire 64 is fixedly mounted on the central shaft 4;

[0033] A sliding ball 71 is fixedly mounted on one end of the first thin wire 63 away from the slider 62, and a fixed ball 72 is fixedly mounted on one end of the second thin wire 64 away from the central axis 4;

[0034] When the middle axis 4 rotates, the first thin wire 63 and the second thin wire 64 will be driven to rotate, and at the same time, the first thin wire 63 and the second thin wire 64 will be swung to a horizontal state due to the centrifugal force through the fixed ball 72 and the sliding ball 71. At this time, the first thin wire 63 and the second thin wire 64 are in a taut state. With the rapid rotation of the middle axis 4, the first thin wire 63 and the second thin wire 64 will cut off the shrimp shells, and at the same time, the shrimp shells will be crushed by the fixed ball 72 and the sliding ball 71.

[0035] In another embodiment of the present invention: a vertical rod 610 is fixedly installed on the side wall of the slider 62, a tooth plate 69 is fixedly installed on the vertical rod 610, a fixed frame 611 is fixedly installed on the inner wall of the central axis 4, a connecting member 67 is rotatably installed on the fixed frame 611, a connecting plate 65 is fixedly installed on one end of the connecting member 67 located outside the central axis 4, a sleeve frame 66 is fixedly installed on the connecting plate 65, the sleeve frame 66 is sleeved on the second thin wire 64, and a gear 68 is fixedly installed on the connecting member 67;

[0036] A top wave ring 61 is fixedly mounted on the inner wall of the grinding cylinder 2, and the bottom end of the top wave ring 61 is annular and wavy;

[0037] When the middle shaft 4 rotates, the second thin wire 64 and the first thin wire 63 will be swung and rotate rapidly, and the first thin wire 63 and the second thin wire 64 are made of metal wire or high-strength nylon wire, so that the first thin wire 63 and the second thin wire 64 can perform powerful cutting when they rotate rapidly. When the shrimp shell is put into the grinding cylinder 2, the first thin wire 63 and the second thin wire 64 rotate rapidly to repeatedly cut the shrimp shell and crush it. At the same time, the sliding ball 71 on the first thin wire 63 and the fixed ball 72 on the second thin wire 64 will also collide with the shrimp shell when they rotate to crush it.

[0038] When the second thin wire 64 rotates, the fixed ball 72 thereon will rotate along the bottom end of the top wave ring 61. At this time, the fixed ball 72 is always attached to the bottom end of the top wave ring 61. Therefore, as the fixed ball 72 rotates, it will float up and down. As the fixed ball 72 floats up and down, the fixed ball 72 will drive the second thin wire 64 to swing up and down. At this time, the second thin wire 64 will drive the sleeve frame 66 to rotate up and down. At this time, the sleeve frame 66 will drive the connecting member 67 to rotate through the connecting plate 65. The connecting member 67 and the gear 68 are coaxial. Therefore, as the connecting member 67 rotates, the gear 68 will also rotate synchronously. Refer to Figure 4Since the gear 68 and the toothed plate 69 are meshed, when the fixed ball 72 contacts the wave crest at the bottom end of the top wave ring 61, when the second thin wire 64 swings downward, the sleeve frame 66 will drive the connecting member 67 to rotate downward, and the gear 68 on the right will rotate clockwise. At this time, the toothed plate 69 will rise. With the rise of the toothed plate 69, the first thin wire 63 will continue to move outward. At this time, relative sliding occurs between the first thin wire 63 and the second thin wire 64, and the sliding ball 71 on the first thin wire 63 will slide on the second thin wire 64. With the sliding ball 7 1 slides, the shrimp shells can be squeezed and crushed between the sliding ball 71 and the fixed ball 72, and when the fixed ball 72 moves to the trough, the fixed ball 72 will swing upward to drive the second thin wire 64 to swing upward, at this time the sleeve frame 66 rotates upward, and the right gear 68 rotates counterclockwise to drive the tooth plate 69 to move downward, at this time the slide plate will move downward to pull the first thin wire 63 to move toward the middle axis 4, with the continuous rotation of the fixed ball 72, the sliding ball 71 will continue to slide on the second thin wire 64 to cooperate with the fixed ball 72 to squeeze and crush the shrimp shells.

[0039] In another embodiment of the present invention: a round rod is fixedly mounted on the inner wall of the grinding cylinder 2;

[0040] The portion of the first thin wire 63 located inside the grinding cylinder 2 is formed at a 90-degree angle by a round rod, so that the end of the first thin wire 63 close to the slider 62 is vertically arranged, while the end located outside the central axis 4 can be rotated to a horizontal arrangement.

[0041] In another embodiment of the present invention: a group of first thin lines 63 is provided with two, and the two first thin lines 63 are respectively located at the upper and lower ends of the second thin line 64;

[0042] The first thin line 63 and the second thin line 64 are arranged in parallel after being flattened, and a gap is left between the first thin line 63 and the second thin line 64 .

[0043] In another embodiment of the present invention: a avoidance hole 41 is provided on the central axis 4;

[0044] The connecting member 67 passes through the avoidance hole 41 . When the sleeve frame 66 rotates up and down, the sleeve frame 66 rotates, which drives the connecting member 67 to rotate. At this time, the connecting member 67 rotates in the avoidance hole 41 without abutting against the central axis 4 .

[0045] In another embodiment of the present invention: an inner expansion plate 73 is fixedly mounted on the sliding ball 71, and an outer expansion plate 74 is fixedly mounted on the fixed ball 72;

[0046] A grinding channel is formed between the inner expansion plate 73 and the outer expansion plate 74, and the outer expansion plate 74 is opened in an "eight" shape. As the first fine wire 63 and the second fine wire 64 rotate, they rotate along the opening direction of the outer expansion plate 74. At this time, the opening of the outer expansion plate 74 will allow some shrimp shells to enter, while the large shrimp shells will be blocked by the inner expansion plate 73, and some broken shells that meet the further grinding standards will enter the grinding channel. When the fixed ball 72 moves up and down at the bottom end of the top wave ring 61, the sliding ball 71 will slide on the surface of the second fine wire 64. At this time, the sliding ball 71 will drive the inner expansion plate 73 to move, and with the relative movement between the inner expansion plate 73 and the outer expansion plate 74, the broken shells in the grinding channel will be further ground.

[0047] In another embodiment of the present invention: grinding balls are fixedly mounted on the ends of the inner expansion plate 73 and the outer expansion plate 74 close to each other;

[0048] The grinding balls are staggered, and as the crushed shells enter, the grinding balls on the inner expansion plate 73 and the outer expansion plate 74 will move relative to each other, so that the crushed shells are rubbed, squeezed and ground between the grinding balls, thereby achieving a better grinding effect.

[0049] In another embodiment of the present invention: an inner ring 83 is vertically slidably mounted on the central axis 4, a long plate 82 is fixedly mounted on the inner ring 83, an outer ring 81 is fixedly mounted on the long plate 82, and a filter is fixedly mounted between the outer ring 81, the inner ring 83 and the long plate 82;

[0050] The size of the sliding ball 71 is larger than the size of the fixed ball 72;

[0051] The middle axis 4 is provided with a plurality of first thin wires 63, second thin wires 64 and a top wave ring 61, wherein the size of the sliding ball 71 is larger than that of the fixed ball 72. When the fixed ball 72 slides along the bottom end of the top wave ring 61, the sliding ball 71 will rotate accordingly. As the sliding ball 71 rotates, due to the larger size of the sliding ball 71, the sliding ball 71 will abut against the filter screen or long plate 82 above it, so that the inner ring 83 moves upward on the middle axis 4. Therefore, when the first thin wire 63 and the second thin wire 64 are rotating and cutting, as the fixed ball 72 slides on the bottom surface of the top wave ring 61, the inner ring 83 moves upward on the middle axis 4. The up and down swinging of the second thin wire 64 will simultaneously drive the sliding ball 71 to move up and down, and as the sliding ball 71 moves upward, the sliding ball 71 will knock and vibrate the filter screen or the long plate 82, and the materials stuck in the filter screen will be shaken off, and as the sliding ball 71 knocks upward, the entire filter screen will move upward with the inner ring 83, and in this case, the shrimp shells on the filter screen will also be shaken up and thrown up, and the thrown up shrimp shells will be quickly cut around by the first thin wire 63 and the second thin wire 64 above, so as to prevent the shrimp shells from always accumulating on the filter screen and being unable to be cut and broken by the first thin wire 63 and the second thin wire 64 above;

[0052] The mesh size of each layer of filter screen becomes smaller as it goes downward, so the incoming shrimp shells can be ground continuously, making the grinding more refined;

[0053] Further, refer to Figure 4 , the slider 62 in one group can be set as two independent sliders 62. At this time, the two independent sliders 62 are both equipped with toothed plates 69 through the vertical rods 610, and are respectively meshed and connected with the gears 68 on both sides one by one. Therefore, when the positions of the two groups of first fine wires 63 and second fine wires 64 on the same layer at the crests or troughs of the top wave ring 61 are not uniform, the two groups of sliders 62 can adaptively slide up and down respectively, so that the first fine wires 63 and second fine wires 64 on both sides will not interfere with each other.

[0054] In another embodiment of the present invention: a groove is formed on the collecting box 3, and the size of the groove matches the size of the central axis 4;

[0055] The collecting box 3 can be inserted into the grinding cylinder 2 through the groove, thereby preventing the collecting box 3 from abutting against the central axis 4.

[0056] In another embodiment of the present invention: a fixing plate 5 is fixedly mounted on the base 1, and the size of the fixing plate 5 and the groove are matched;

[0057] When the collecting box 3 is inserted into the grinding cylinder 2, as the collecting box 3 is continuously inserted, the groove on the collecting box 3 will be stuck on the fixing plate 5, so as to fit tightly. At the same time, the height of the fixing plate 5 can be higher than the collecting box 3, and the top of the fixing plate 5 can be chamfered, so that the powder falling on the fixing plate 5 can slide into the collecting box 3.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
